Bug ID: 20552
Summary: Binutils: bad relocation with arm cortex-M toolchains.
Product: binutils
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: romain.naour at gmail dot com
Target Milestone: ---
Hi,
Binutils (2.25.1 and 2.26.1) fail to build on arm Cortex-M4 architecture due to
-Os optimization [1].
libtool: link:
/home/buildroot/autobuild/run/instance-3/output/host/usr/bin/arm-linux-gcc -w
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os
-Wl,-elf2flt -static -static-libstdc++ -static-libgcc -Wl,-elf2flt -static -o
strings strings.o bucomm.o version.o filemode.o ../bfd/.libs/libbfd.a
../libiberty/libiberty.a -lintl -lz -lm
ERROR: reloc type R_ARM_THM_MOVW_ABS_NC unsupported in this context
ERROR: reloc type R_ARM_THM_MOVT_ABS unsupported in this context
2 bad relocscollect2: error: ld returned 1 exit status
Using O1, O2 or O3 allow to build Binutils correctly.
Best regards,
Romain Naour
